When the prefix suppresion/enabling logic was added, I forgot to add an extra %, which ended up chopping off the strings: Before: # perf trace -e *mmsg --map-dump syscalls [299] = 1, [307] = 1, DNS Res~ver #3/14587 sendmmsg(106<socket:[3462393]>, 0x7f252b0fcaf0, 2, MSG_) = 2 chronyd/1053 recvmmsg(4, 0x558542ca5740, 4, MSG_, NULL) = 1 DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2 DNS Res~ver #2/14444 sendmmsg(146<socket:[3457863]>, 0x7f2521a7aaf0, 2, MSG_) = 2 DNS Res~ver #2/14445 sendmmsg(106<socket:[3461475]>, 0x7f252ab09af0, 2, MSG_) = 2 DNS Res~ver #3/14587 sendmmsg(148<socket:[3460636]>, 0x7f252b0fcaf0, 2, MSG_) = 2 DNS Res~ver #2/14444 sendmmsg(146<socket:[3457863]>, 0x7f2521a7aaf0, 2, MSG_) = 2 ^C# After: # perf trace -e *mmsg --map-dump syscalls [299] = 1, [307] = 1, NetworkManager/17467 sendmmsg(22<socket:[3466493]>, 0x7f28927f9bb0, 2, MSG_NOSIGNAL) = 2 pool/17478 sendmmsg(10<socket:[3466523]>, 0x7f2769f95e90, 2, MSG_NOSIGNAL) = 2 DNS Res~ver #3/14587 sendmmsg(121<socket:[3466132]>, 0x7f252b0fcaf0, 2, MSG_NOSIGNAL) = 2 chronyd/1053 recvmmsg(4, 0x558542ca5740, 4, MSG_DONTWAIT, NULL) = 1 Socket Thread/17433 sendmmsg(121<socket:[3460903]>, 0x7f252668baf0, 2, MSG_NOSIGNAL) = 2 ^C# Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Fixes:c65c83ffe9("perf trace: Allow asking for not suppressing common string prefixes") Link: https://lkml.kernel.org/n/tip-t2eu1rqx710k6jr4814mlzg7@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
